1. Send the first message from TN
In the first message (1), the initiator generates a proposal it
considers adequate to protect traffic for the given situation. The
Security Association, Proposal, and Transform payloads are included
in the Security Association payload (for notation purposes).
2. Receive the second message from NUT
In the second message (2), the responder indicates the protection
suite it has accepted with the Security Association, Proposal, and
Transform payloads.
3. Send the third message from TN
In the third (3) message, the initiator send keying material
used to arrive at a common shared secret and random information
which is used to guarantee liveness and protect against replay attacks.
4. Receive the fourth message from NUT
In the fourth (4) message, the responder send keying material
used to arrive at a common shared secret and random information
which is used to guarantee liveness and protect against replay attacks.
5. Send the fifth message from TN
In the fifth (5) message, the initiator send identification
information and the results of the agreed upon authentication
function. The signed data, SIG_I is the result of the negotiated
digital signature algorithm applied to HASH_I.
6. Receive the sixth message from NUT
In the sixth (6) message, the responder send identification
information and the results of the agreed upon authentication
function. The signed data, SIG_R is the result of the negotiated
digital signature algorithm applied to HASH_R.
The first to the sixth message must be exchanged correctly.
Check *1
Security Association Payload Format must be base on description of RFC.
Check *2
Key Exchange and Nonce Payload Format must be base on description of RFC.
Check *3
Identification and Signature Payload Format must be base on description of RFC.
And must conform to above Configuration.

4. Introduction
(omit)
IKE implementations MUST support the following attribute values:
- DES [DES] in CBC mode with a weak, and semi-weak, key check
(weak and semi-weak keys are referenced in [Sch96] and listed in
Appendix A). The key is derived according to Appendix B.
- MD5 [MD5] and SHA [SHA].
- Authentication via pre-shared keys.
- MODP over default group number one (see below).
In addition, IKE implementations SHOULD support: 3DES for encryption;
Tiger ([TIGER]) for hash; the Digital Signature Standard, RSA [RSA]
signatures and authentication with RSA public key encryption; and
MODP group number 2. IKE implementations MAY support any additional
encryption algorithms defined in Appendix A and MAY support ECP and
EC2N groups.
(omit)
5. Exchanges
There are two basic methods used to establish an authenticated key
exchange: Main Mode and Aggressive Mode. Each generates authenticated
keying material from an ephemeral Diffie-Hellman exchange. Main Mode
MUST be implemented; Aggressive Mode SHOULD be implemented. In
addition, Quick Mode MUST be implemented as a mechanism to generate
fresh keying material and negotiate non-ISAKMP security services. In
addition, New Group Mode SHOULD be implemented as a mechanism to
define private groups for Diffie-Hellman exchanges. Implementations
MUST NOT switch exchange types in the middle of an exchange.
